Given numbers are 884,720,689,340
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 884,720,689,340 is 8433360.
Find LCM of 884,720,689,340 with Prime Factorization
| 2 | 884, 720, 689, 340 |
| 2 | 442, 360, 689, 170 |
| 5 | 221, 180, 689, 85 |
| 13 | 221, 36, 689, 17 |
| 17 | 17, 36, 53, 17 |
| 1, 36, 53, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 17 x 1 x 36 x 53 x 1 = 8433360
Therefore, the lowest common multiple of 884,720,689,340 is 8433360.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
884 x 720 x 689 x 340 = 149101804800
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
689 : 1, 13, 53, 689
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 884,720,689,340, is 1.
Now, the common factors can be found like this.
884:2x 2x 13x 17
720:2x 2x 2x 2x 3x 3x 5
689:13x 53
340:2x 2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 5x 13x 17 = 17680
Therefore, the value for common factors is 17680.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 149101804800/(1x17680)
LCM = 149101804800/17680
LCM = 8433360
Thus, we can understand that the LCM of 884,720,689,340 is 8433360.
